Hey Product Hunt 👋 Founder here. I built EyeZenith because I got tired of needing a $400 watch to track basic wellness signals. Turns out your iPhone's TrueDepth camera + Apple's Vision framework can read a *lot* about how you're doing — if you process it on-device. What EyeZenith does today (all in 60s scans): • Eye-tracking: saccade + fixation analysis → focus & cognitive load • Camera PPG: heart rate variability when no Apple Watch is paired • Screen-distance detection: real eye-strain warnings, not just timers • Reading wellness: long-form sessions with read-along word tracking • Breathing & soundscape: 4-7-8 guided rhythm + ambient stress detection What it doesn't do: • It is not a medical device. It will not diagnose anything. • It does not send your images, voice, or biometrics to a server. Ever. What I'd love feedback on: • Onboarding flow — does it explain the "why" fast enough? • Paywall — is the value clear before the ask? • Any features you wish existed? Happy to answer everything throughout the day. 🙏
